Roughly the size of a gnome, this pet is one of the largest of all vanity pets. It may be used by non-engineers.

As of roughly Patch 5.2, Umi Rumplesnicker no longer offers to train engineers the schematic for this pet. The quest, A Yeti of Your Own, was either removed from the game or was unintentionally severed from the quest chain. It's unknown if the quest will return in a future patch.

Although the recipe for the Tranquil Mechanical Yeti is currently unobtainable, engineers that learned how to make this pet prior to the quest's disappearance can still craft this pet.

Great Nuke pet that has the ability to cast 2 weather effects a damage increase and a Ion Cannon. You have 4 nuke options and can swap him out with pets that use Rebuild or Wish to heal his life back up. As for getting him, ask around trade chat for someone who can make him for you if there isn't one in the AH. Don't forget to Tip!

A friendly engineer will make this for you, and you want at least one of these on your team. They come in only one breed H/B. Save Ion Canon ability until you know it will kill and you can recover. Call Lightning is a double edged sword, but look at the damage it does initially, especially vs beasts. Save it for the end of the battle. Early in battle only if using team strategy.

Tranquil Mechanical Yeti was the first pet I bought at the AH and first pet I levled to 25. And even though other Mechanicals seem to have higher ratings, I've always found that my Lil Bigfoot is my go-to favorite Mechanical with its super-beast killing powers. Only my Iron Starlette aka 'Toni Stark' gives my Yeti a run for his money!

This pet is a beast. One of the best Mechanical pets in my opinion. His Ion Cannon + Lightning storm is a fantastic combination. It does a ton of damage usually well over a 1000 damage. The only draw back to Ion is that you are unable to attack for 2 rounds. It's best used as a finishing move or a last ditch attack before death.

I was not aware that the recipe has been removed. Good thing I got it on my mechanic before it was removed. Maybe I should take up selling it on my server.

Based Wowhead comments, it appears the quest to receive these plans, "A Yeti of Your Own", was removed from the game in 5.2. It is unclear if this was a mistake or intentional, or whether it will be returning.

Has anyone recently done the quest line as an engineer to get this pet? I spoke with a GM after doing the required quest and they said you had to be a goblin engineer and that plan was taken out of the game. Has anyone recently done this or can confirm otherwise?

Great battle pet and a great money maker for Engineers. If you can mine the metal yourself then you can get the Elemental Air and Elemental Earth in the same zone in Arathi highlands and the Globe of Water in Swamp of sorrows. The only thing I need to buy is the Cured Rugged Hide. These pets go for 400+ on the auction.

This guy has soome of the best combos of any pet. Supercharge + call lightning = dead beast, + call blizzard = dead mech. Follow a call lightning with flurry = dead critter, and does a lot of damage vs most everything else but flying and elemental, but you should never use a mech vs elemental, anyway.

I have heard that if you do the quest and abandon engineering (For whatever reason) and learn it again at some point in the future you can relearn it from the quest giver provided your levels are high enough. If this isn't true let me know as I haven't been able to confirm it (Nor do I want to try <.<;)

Update to Zenon's recipe list, the Deeprock Salt needs to be Refined Deeprock Salt (leatherworker is only one who can refine, with a Salt Shaker, but make sure the leatherworker can refine it also), and missing is a Globe of Water (two), also required
